Hi Rachel,
I didn't see any settings to update this but think Airtable's been focusing more on building out their interfaces. I noticed that when you build an interface page and select the Kanban view, it does show a total for each column, which enables you to hide/display other associated data (though it doesn't have the aggregate total).
For example:
![rachuang_1-1721404803896.png rachuang_1-1721404803896.png](/t5/image/serverpage/image-id/35505i117F698967C0EBBC/image-size/medium?v=v2&px=400)
Hope that helps!
Best,
Rachel
